The last problem I had like this Richard was in Reno, 1979.
A Corp of Engineers guy told me I couldn't use toggles in precast
hollow core concrete panels because it wasn't metal lath and plaster.
Since then though it seems like all the AHJs i deal with get smarter
every year.

Quoting Richard Mote <[email protected]>:
I have a AHJ that is questioning the use of Flex Drops especially
the Victaulic ones. He says that they are so flexible that when a
sprinkler goes off the jet effect is going to lift the sprinkler up
through the ceiling. I told him that the drops are mechanically
attached to the ceiling grid and in order to lift up they would have
to lift the entire weight of the ceiling grid, ceiling tiles, the
lights and HVAC diffusers. His answer prove, it either by letter
from the manufacturer or from someone a lot higher up the food chain
than either he or I am. Or something specific in NFPA 13 that says
he is wrong.
